help ! walt smith pink birdnest with yellow tip turning red

As a frag grows into a colony it is not uncommon for color shifts. A frag could only have color in the tips, whereas a 14" specimen of the same species could turn solid. I am using a pretty rough example, however I feel most will agree there are color shifts as colonies mature over years.
 
I have a Doc Fosters and Smith diver's den Seriatopora hystrix.

In the system of the original guy that ordered it, he had pink rose base with green tips, in my system it's red rose with very slight tint of a greenish white and it's even went pinkish white tip with very slight hue of green, gave some to my friend and it's almost entirely the green color the fellow I got it from green tips were.

Nutrient, additves, light, all impact different corals differently in different systems to varying degrees. I believe the mix of all three tend to influence pigments and since systems vary it stands to reason colors will not be the same.
